Ive got one for my G19. From the get-go, it was kinda uncomfortable but does get better. And since I wasnt used to that style, it was a PITA to get situated. But, its getting better the more I use it. Most of the time, i carry in a Blackhawk kydex OWB with a light jacket that partial covers it. (Open carry is allowed here.)

I gotta add tho, I really havent wore it enough to give it a good and thorough evaluation. It does seem to be breaking in well. I really have no regrets on the purchase. The carry angle is fine, retention is fine, ample adjustments on both.

I have several foxx holsters .
It took about a week of constant wear to break in and fit well. Very comfortable . Wish they had the leather loop option but they domt they do have several other clip options . I bought leather loops for my foxx from AlienGear
